July 10.—We were all anxiety this day. Barca Gana was nearly one thousand strong, and about four hundred Dugganahs joined him, besides furnishing him with nearly one hundred horses. Amanook was one of the sheikh’s most troublesome remaining enemies; the sheikh had, on various occasions, and lastly, when he joined the Begharmis in their attack on Bornou, very severely crippled him, and destroyed more than half his force: the design now was to annihilate the remainder, and secure, if possible, the person of this inveterate foe, who kept alive the hostile feeling both on the Begharmi and Waday side. Amanook, however, was not to be taken by surprise, and he gave the sheikh’s troops such a proof of what might be done by a handful of men, bold of soul, and determined to defend an advantageous situation, that they will not easily forget. Just before sunset a Fezzanneer, who had lately entered into the sheikh’s service, returned to the camp, giving an account of Barca Gana’s complete discomfiture, and Bellal and myself immediately mounted our horses in order to learn the particulars. The Tchad[52], which in this part forms itself into innumerable still waters, or lakes of various extents, and consequently leaves many detached spaces of land or islands, always afforded the La Sala Shouaas, and the Biddomah, natural defences, which their enemies had ever found it extremely difficult to conquer. In one of these situations, these very La Salas, with Amanook at their head, kept the sultan of Fezzan, with two thousand Arabs, and all the sheikh’s army, several days in check, and killed between thirty and forty of the Arabs before they surrendered. On this occasion Amanook had taken possession of one of these islands, which, to attack with horsemen alone, in front of an opposing enemy, was the height of imprudence. A narrow pass led between two lakes to a third, behind which Amanook had posted himself with all his cattle, and his people, male and female: the lake, in front of him, was neither deep nor wide, but full of holes, and had a muddy deceitful bottom on the side from whence the attack was made.
